Clinical Utility

Measurement of fructosamine indicates glycemic control over extended periods of time. Fructosamine values reflect glycemic control for the previous 2-3 weeks. Changes in fructosamine values alert the physician to deteriorating glycemic control earlier than changes in Hemoglobin A1c values. Fructosamine levels decrease more rapidly than Hemoglobin A1c, when diabetic patients are brought under better control.
